ASSGNGR TO AMERICAN STEEL BRAKE RIGGTNG Application filed December 11, 1929.

The invention relates to brake rig-ging'-t`0r railway earsa and has reference more particularly to a type ot rigging wherein brake shoes are applied to both sides of car wheels and o' known as the clasp type.

A 'further object is to provide a brake rigging of the above type wherein the actuating levers Yfor the live truck levers and their connecting links form a llexible connection' so 4hat motion ol the bolster due to the action of its supporting springs Will not be transmitted to those brake parts rigidly secured to the frame. Preferably the construction of the truck traine and bolster provides for the bolster to be spring supported from the trame. This allows the bolster to have motion independent of the frame and necessi tates a lleiible connection in the brake rig- ,einer between those parts rigidly secured to the` trame, and those secured to the bolster, which has particularly been provided 'for by the improved structure ot the present invention.

A vet further object to provide a brake rigging of simple construction which will be light in weight. and effective and positive in operation.

lith these and various other objects in view. the invention may consist ot certain novel features of' construction and operation` as will be more tully described and 'particularly pointed out in the specification, drawings and claims :ipgreended hereto.

1n the iliawinefs1 which illustrate an embodiment ot" the device and wherein like reterezire characters are used to designate like parts-- Figure 1 is a fragmentary top plan view ot' one vform of clasp type of brake embodying the improved construction of the present 0 invention semi ne. 4135/241 Figure 2 is a longitudinal elevational View of the same;

Figure 3 is a sectional view taken substantially along lin-e 3)-3 of Figure l;

Figure 4 is an end elevation of the arrangement shown in Figure 1.

Although the drawings and description pertain to only one side of the truck, it is understood that the same applies to the other side as well, i. e.7 there is a double set of brake levers and connections.

The improved construction is shown as applied to a tour-wheel truck comprising a truck frame and car wheels 11 having a transverse bolster l resilientlv mounted centrally oit the trame tor movement relative thereto. The wheels on each side ot' the truck frame are engaged by brake shoes 13 and 1,4 designating the inside and outside shoes respectively. Brake heads l5 their corresponding' inside shoes and heads 16 engage-'- their outside shoes. The former are in turn suspended from the frame by hangers 17 and are secured to the outer end ot transversely extending brake beams 18 and 19 as shown in Figure 1. The brake heads with their correspoinling,r .beams 18 and 19 are in this manner suspended Yfrom the trame 10.

'l'he outside brake heads 16 are pivotally secured to the dead truck levers 20 which have pivotal engagement with the trame 10 as at 2l. Brake beams 22 are also employed eX- t-ending transversely of the frame said connection boing at a position on the dead truck levers intermediate the ends thereof for joining` the dead truck levers 2t) on both sides ot the trame. Spacing or tie members 23 (Figure 4) are provided extending transversely and substantially parallel with the beams 22, and serve to join the brake shoes 16 on both sides of the traine so that the shoes are maintained in alignment with the tread of the car wheels.

Live truck levers are located to the inside of the car wheels at both sides of the truck and designated 24 and 25. The lever 24 is connected at its lower end to a fulcrum member Q6 secured to the brake beam 18, and the lever Q5 is connected in a similar manner to the brake beam 19 by fulcrum member 27.

bolster and a plurality of wheels, brake beams provided with brake shoes supported from said frame and disposed on both sides of each of said wheels, two live truck levers pivotallv connected at their lower ends to the brake beams at one side of the wheels, two dead truck levers pivotally connected to the brake beams at the opposite side ofthe wheels, other levers one of which is pivoted to said bolster, clevises pivotally connecting said other levers with the upper end of said live truck levers, and a tie rod connecting said other levers a nd supported upon said bolster.

In a brake rigging, the combination with a wheeled truck frame having a frame niember, of dead truck levers at one side of wheels, live truck levers located on the opposite side of the wheels` coupling rods connecting .said live and dead levers, other levers. one of which is connected to a certain live truck lever, the. other beingl connected to another live truck lever and to said frame member. means connecting said other levers supported on said frame member, and operating means connected to one of the other levers for op @rating tbe truck levers.
